The six-months restoration of the iconic glasshouse in the walled kitchen garden at Clumber Park has been completed.

Spanning four acres, the garden is one of the grandest surviving 18th Century walled gardens in England.

Work to restore and redecorate its Grade II listed conservatory and palm house began last August.

Reaching over 137 metres (450 feet), and split into 12 sections, the glasshouse is the longest in the care of the National Trust. It was installed by the 7th Duke of Newcastle and completed in 1910. The design and construction is attributed to horticultural builders James Gray.

After suffering timber rot, glazing breakages, and significant timber decay over the years, restoration work involved extensive timber splice and resin repairs to retain as much of the original timber structure as possible.

The glazing, of which the roof alone has more than 800 individual panes, was removed, cleaned, and reused where possible.

There was also masonry and repointing works, lime washing of walls, rewiring the palm house climbing wires, and repair and redecoration of rainwater goods.

The work was carried out by heritage joinery specialists Jericho Joinery Ltd, of Newark, and funded by gifts in wills from National Trust supporters.

Now the work is complete, visitors can access the full breadth of the building, which also houses a tools and vineries museum, apple store and drying room, and a former gardeners’ mess room.

The Clumber Park Gardens team, which consists of seven staff and more than 45  volunteers, create spectacular displays in the conservatory of the glasshouse each season, and this spring are organising two events to showcase the restored glasshouse and walled kitchen garden.

Rhubarb Week, Monday 15 – Saturday 20 April, 10am-4pm. The walled kitchen garden is home to the National Rhubarb Collection, with over 130 varieties. The event includes rhubarb tasting, a rhubarb trail and tours of the garden.

Blossom Week, Saturday 20 – Sunday 28 April. The National Trust’s Festival of Blossom is a shared national celebration of nature, which takes place each spring. This year, enjoy many blossom-themed activities including Japanese folklore storytelling, a photography walk, pop-up floristry, and poetry workshops.
